Sentences with phrase «prey density»

«Because of small and isolated nature of these high prey densities in these reserves, such adaptions are helpful for conservationists trying to save all three.»

But the research development of the techniques to count prey and tigers and doing studies in different sites across India with high and low prey densities show very clearly that the number of tigers is linked to the number of prey in a very, very strong relationship.

Tagged whales varied the depths of their feeding dives to: i) track diurnal changes in the vertical distribution of krill; ii) match changes in prey density at depth; and / or iii) forage along edges of the prey aggregation (Figure 2).

That a simple change in the concentration of food could lead to such unusual behavior speaks to how prey density can drive the evolution of new hunting strategies, Cade suggested.

We used high - resolution multisensor digital tags attached to foraging blue whales (Balaenoptera musculus) with concurrent acoustic prey measurements to quantify foraging performance across depth and prey density gradients.

Across India, tiger abundance is strongly correlated with prey density [20] and both depend on strict controls on hunting.

Risk was also associated with large body size, high - quality habitat, high prey density, winter dispersal, inclement weather, and intraspecific interactions.

Amur tigers have the largest home range of any tiger subspecies because they have to search over large areas to find food due to low prey densities.

Contrary to previous paradigms, we demonstrate that blue whales are not indiscriminate grazers but instead switch foraging strategies in response to variation in prey density and depth to maximize energetic efficiency.

We wanted to pass along a recent manuscript on optimal foraging in blue whales as a function of oxygen use and prey density.

Our analyses show that at low prey densities, blue whale feeding rates and energy intake were low to minimize oxygen use, but at higher prey densities feeding frequency increased to maximize energy intake.

Blue whales change their foraging strategies relative to prey density.
